Cermet - an overview ScienceDirect Topics

Cermets are constituted of a ceramic matrix bonded by a metallic binder. The metal improves the toughness and the thermal shock resistance of the ceramic. Two major groups of cermets can be defined: the hardmetals, which are based on carbides, nitrides, borides, and silicides of the fourth to sixth element groups, and the oxide cermets.
